Kuchengeta kwemvura kwehydroxyprupyl methylcellose ether
Kuchengetwa kwemvura kwemvura yakaoma musanganiswa motsi kunoreva kugona kwemutema kubata uye kukiya mvura. Iyo yepamusoro iyo viscosity ye hydroxyprosll methylcellose ether, zvirinani kuchengetwa kwemvura. Nekuti chimiro cheCellulose chine hydroxyl uye ethygens, iyo okisijeni maatomu ehydroxyl uye kuti mvura yemahara inosungirwa mvura, kuti mvura yemahara inova nemvura uye inopinda mumvura, nekudaro ichiridza chikamu chekuchengeta mvura.
Solubility ye hydroxypronyl methyl cellelose ether
1. Coarse partle cellulose ether iri nyore kuparadzira mumvura pasina kuunganidzira, asi chiyero chekunyungudika chinononoka. Cellulose ether pazasi 60 mesh inogumburwa mumvura kwemaminetsi makumi matanhatu.
2. Kwakanaka partle cellelose ether iri nyore kuparadzira mumvura pasina kuunganidzwa, uye chiyero chekunyungudika chiri pakati nepakati. Cellulose ether pamusoro pe80 mesh inogumburwa mumvura kwemaminitsi matatu.
3. Ultra-yakanaka tikamu cellelose eth inopararira nekukurumidza mumvura, inodurura nekukurumidza, uye inogadzira viscosity nekukurumidza. Cellulose ether pamusoro pe120 mesh inodonha mumvura kwemasekondi gumi nemashanu.
Iyo yakanaka iyo zvidimbu zvehydroxyprupyl methylcellose ether, zviri nani kuchengetwa kwemvura. Pamhepo yemakonzo-yakagadzirwa cellulose ether ichipinda nekukurumidza mushure mekufonera nemvura uye inoumba gel phenomenon. Iyo glue inoputira izvo zvekudzivirira mamorekuru emvura kuti uenderere mberi nekupinda. Dzimwe nguva hazvigone kugadzikana pamwe nekunyungudutswa kunyangwe mushure menguva refu kusimudzira, kuumba makore ekuwedzera furccucleent solution kana kuunganidzwa. Izvo zvidimbu zvakanaka zvinopararira uye nyungudika nekukurumidza mushure mekufonera nemvura kuti ugadzire yunifomu viscosity.
PH Kukosha kweHydroxyPropyl methylcellose ether (kudzoreredza kana kutanga simba maitiro)
Iyo PH Kukosha kweHydroxyPropyl methylcellose ether Vagadziri kumba uye kunze kwenyika inodzorwa pamakore manomwe, iri mune acidic nyika. Nekuti kuchiri nhamba yakakura yeAnhydroglucose kurira kwemhete mune moleky chimiro cheCellulose ether, iyo Anhydroglucose mhete iboka guru rinokonzeresa kudzoreredzwa. Iyo Anhydroglose mhete inogona kuita calcium ion muiyo simende hydation yekupa shuga-calcium makomputa, kudzivirira kuumbwa kweCalcium hydroxide uye calcium munyu makristeni, uye kunonoka hydration ye simende. maitiro. Kana iyo pH kukosha iri muAlkaline State, durari ichaonekwa mune yekutanga-simba mamiriro. Iye zvino mafekitori mazhinji anoshandisa sodium carbonate kugadzirisa iyo ph kukosha. Sodium kabhoni ndeye mhando yekukurumidza-kurongedza mumiririri. Sodium carbonate inovandudza mashandiro ezvikamu zveSement zvikamu, zvinosimudzira kubatana pakati pezvikamu, uye kuenderera kunovandudza zvevatenzi vevhu. Panguva imwecheteyo, sodium carbonate nekukurumidza inosanganisa necalcium ion mudururu kusimudzira kuumbwa kweEtitringe, uye chidimbu chinobatanidza nekukurumidza. Naizvozvo, iyo pH kukosha inofanirwa kuchinjirwa zvinoenderana nevatengi vakasiyana mukugadzira chaiyo yekugadzira.
Mhepo yekushambadzira zvivakwa zve hydroxyprupyl methyl cellelose ether
Iyo mhepo-inopinda mhedzisiro yehydroxyprupyl methylcellose ether inonyanya nekuti cellulose ether zvakare rudzi rwechisimba. Iyo yekubvumirana chiitiko che cellulose ether inonyanya kuitika pane iyo gasi-mvura-yakasimba interface. Kutanga, kuiswa kwemhepo mabhuru, ichiteverwa nekupararira uye kunyorova maitiro. Cellulose Ether ine Alkyl mapoka, ayo anoderedza zvakanyanya kusawirirana uye kusangana kwesimba remvura, zvichiita kuti zvive nyore kugadzira madiki mazhinji emabhuru panguva yekukurudzira mhinduro.
Gel Properties yeHydroxyPropyl Methyl Cellelose ether
Mushure meiyo hydroxyprupylmyl methylcellose ether yakanyungudutswa mudhaka, iyo nzira yeiyo hydroxproprop ioni . Nekudaro, apo iyo menrosite matsori iri pasi pekumanikidzwa, iyo polymer haigoni kutamba yakaomarara basa, saka simba uye kupeta ratio yekudzikira kwemota.
Firimu kugadzirwa kwehydroxyprupyl methyll cellelose ether
Mushure mekunge HydroxyPropyl methyl cellel cellulose erdration inowedzerwa hydration, iyo yakatetepa yefirimu reLatex inoumbwa pakati peiyo simenti. Iyi firimu ine chisimbiso chisungo uye inovandudza kuoma kwemukati kwemutumbi. Nekuda kwekuchengetwa kwemvura kwemvura kwehydroxyprEpyl methylcellose ether, mamorekuru emvura anochengetwa mukati meiyo simbiso uye nekuvandudzwa kwakazara kwesimba, nekuvandudza kusanganisa kwerukova, uye panguva imwe chete iyo Inovandudza kubatana kweiyo durari, inoita kuti durmarke ive yakanaka plasticity uye kuchinjika, uye inoderedza shrinkage uye deformation yemutyairi.
